Question

I just need one more answer to this. Please someone help!

Answer 1

Answer:

(1,0)

(-2,3)

(5,24)

Step-by-step explanation:

To solve this you can can just plug in the x and y values and see which work

y = x²-1

Lets test (0,1):

1 = 0²-1

1 = -1

This pair does not work, because 1 does not equal -1

Lets test (1,0):

0 = 1²-1

0 = 0

This does work, because 0 equals 0

Lets test (3,5):

5 = 3²-1

5 = 9 - 1

5 = 8

This pair does not work, because 5 does not equal 8

Lets test (5,24):

24 = 5²-1

24 = 25 -1

24 = 24

This pair does work, because 24 equals 24

Lets test (-2,3):

3 = (-2)²-1

3 = 4-1

3 = 3

This pair does work, because 3 equals 3

Lets test (-4,-17):

-17 = (-4)²-1

-17 = 16 - 1

-17 = 15

This pair does not work, because -17 does not equal 15

So the pairs that are on the graph are:

(1,0)

(-2,3)

(5,24)
